Water content,ppm





Lithium difluoro(oxalato)borate;Lithium difluoro(oxalato)borate(1-);LithiuM Oxalyldifluoroborate

The determination of KF

Use MA-1 intelligent Carle Fischer moisture tester to measure water content

Determination of melting point


Micro melting point apparatus WRS-2A, Melting point tubes

Determination of step:

Open switch, stable 20min.

First set the starting temperature than the melting point of the low 10 ℃, heating rate 2 ℃ / min.

The sample was grind as fine as possible and load in a clean, dry melting point pipe ,until the sample was compressed into about 1cm high .When the actual temperature reaches the set temperature and stabilized . Inserted into the capillary with the sample, the simultaneous determination of three.

Determination of iron content

Preparation of standard iron solution

Weigh ammonium iron(III) sulfate [FeNH4(SO4)2·12H2O] 0.863g .Placed in 1000mL volumetric flask, add water to dissolveand add sulfuric acid 2.5mL.Diluted with water to the mark, shake, as the stock solution.

Before use, exact amount of stock solution 1mL, placed in 100mL flask, diluted with water to the mark and shake.

Weigh 1g sample, placed in a crucible.Adding sodium carbonate 2g and mixed.Burning at 740 ℃,the residue is dissolved in dilute hydrochloric acid 15ml , displacing 50mL Nessler colorimetric tube , add dilute hydrochloric acid 4mL and ammonium persulfate 50mg , Diluted with water to make into 35mL, add 30% ammonium thiocyanate solution 3mL, plus the amount of water diluted into 50mL, shaked. If the color, take 1mL standard iron solution into 50mL Nessler colorimetric tube, add water to 25mL,4mL dilute hydrochloric acid and 50mg ammonium persulfate , diluted with water to 35mL, then plus 30% ammonium thiocyanate solution 3mL, plus the amount of water diluted into 50mL, shake comparisons.
